  1. Performance Metric of Convergence Time of Information Flooding in Multi- Domain GMPLS Networks Min Zhang Ding Hui Yongli Zhao Jie Zhang Beijing University of Posts and Telecommunications（BUPT） draft-zhangm-ccamp-metric-00 Haiyi Zhang Yunbin Xu China Academy of Telecommunication Research, MIIT, China（CATR） IETF 79, Beijing 1

  2. Existing RFCs aboutmeasurement in GMPLS networks Multi-domain testing is not mentioned • Test routing protocol in GMPLS networks • RFC5814-signaling protocol • Convergence time vs. Setup delay • RFC5814-setup delay • Convergence of the network • RFC4061-single router control plane 2

  3. Motivation of Convergence time in multi-domain networks Network Events in RFC4062 • Helpful for network failure detection • Link or Neighbor device up • Initialization • Adjacency down • Link down • Online monitoring • Multi-domain measurement 3

  4. Definitions Time Structure • Initial Convergence Time of Information Flooding(CTIF) • CTIF with LSPs • CTIF in single domain • CTIF in multi-domains CTIF-Convergence Time of Information Flooding DBD-Database Description LSU-Link State Update 4

  5. Multi-domain scenario CTIF-Convergence Time of Information Flooding Destination Source Time structure is stored in every control node. Discussion Clock synchronization among all control nodes. Proper waiting time before the affirmation on completion of resource reservation. 5

  6. Next Step Works on test report Refine it according feedback from the meeting or the mailing list Comments are always appreciate 6
